<PRE><B>Question 1137905</B>
standard error(SE) = 17.8/square root(1077) = 0.5424
:
alpha(a) = 1 - (96/100) = 0.04
:
critical probability(p*) = 1 -(a/2) = 0.98
:
critical value(CV) is the z-score associated with p*
:
CV = 2.05
:
Margin of Error(ME) = CV * SE
:
ME = 2.05 * 0.5424 = 1.1119 is approximately 1.11
:
The 96% confidence interval is 15.5 + or - 1.11, which is (14.39, 16.61) 
:
A 96% confidence interval means that we expect that 96% of interval estimates to include the population mean
:
Answer is C.</PRE>
